This invention relates to change makers. It is desirable in merchandising articles sold that the clerk or other seller of the goods, or the one Vin an office who receives the payment, have a ready and effective means for getting the change which is returnable to the customer, payment for which in most instances is by an amount greater than the purchase price so that the difference must be returned; also for changing larger coins into smaller ones. The present-invention is directed to a novel and very practical machine for making change, and of which a number may be used, one for example for each of the commonly used coins, cents, nickels, dimes and the like. A large number of coins in a tubular magazine therefor are applied and a selected number of such coins may be readily removed from the magazine, the number of the coins being determined by selection and operation of manually operated levers, one for each of the number of coins desired. Said coins thus removed are delivered at the front of the machine.

y A primary object and purpose of the present invention is to simplify and reduce the cost of such machines so that their utilization in many places now unequipped may be greatly increased. Many novel constructions, combinations and arrangements of lparts for the eiective attainment of the results desired will appear and be understood, from the following description, taken in connection with the accompanying drawing of a practical embodiment of our invention, in which, Y Fig. 1 vis a iront elevation of the changemaking machine of our invention.

In the construction shown, a frame is provided having two vertical side plates I and 2 spaced from each other, which at their upper ends,-may be connected by a. curved bar 3` and at their lowergends aredsecured to` a. horizontal base 4. A ban 5 extends horizontally between the sides .I and-f2 adjacent their lower ends and back of (Cl. 13S-5) their front edges, and a heavier horizontal bar L 6 extends between and is connected to said sides above the bar 5. Said bars. 5 and 6 at their front sides carry sheet metal holding clips 'I permanently secured inplace` with which a vertical tubular coin holding magazine 8 may-be detachably connected. A lug 8a (Fig. 2) is permananently secured at the rear side of the tube 8 and rests upon the upper edge of the lower tube holding member 'I.

The tubular magazine` 8 at its outer side is vertically slotted at 9. from a short distance below its upper end to withina short distance of its lower end, the slot having a lateral branch at its lower end. A spring actuatedmovable follower I0 is located within the tube 8 and is moved upwardly by a coiled compressionspring, the lowerrnost coin within the tubular magazine resting upon the upper end of the follower. A pin I I is connected with the follower and extends outwardly through the slot 9 so that the follower may be moved to a` lowermost position and held therein by turning the pin into the lateral offset with the coins which are to be used. v The tube at its upper end (Fig. 6), at two different levels, is provided with upwardly and` inwardly curved fingers I2 at opposite sides, whereby when the coins are moved upwardly in the tube by the action of the spring follower, should they have any tendency to stick together at adjacent sides they will be slightly moved horizontally (Fig. 4) to break or disrupt any such tendency to adhesion.

At the upper end portion of the magazine 8 and above the upper end of the slot 9 therein a tubular sleeve I3 is detachably connected by the use of a pin and bayonet slot4 connection I4. Such sleeve is embraced at its rear side by a U-shaped band lofmetal secured thereto by soldering or other similar connection, the forwardly extend-A ing legs of which have .inwardly turned horizontal angesIS and IB extending partly over the upper end. of the tube 8 and against which the uppermost coin carried by the magazine 8 is pressed atr its .opposite side edges. At the rear end/of one of said anges, spaced ears extend upwardly,A between which vanarm I'I is located at one end thereof and Divotally connected, it having a downwardly extending finger I8 between its ends which normally rests against the uppermost coin in the magazine. As shown in Fig. 4 the free. end portion of the arm I'I at its upper edge is widenedinan upward direction for a purposelater-a"v caring. AleverIQo-fat metal and U-shapedv vvtliexle'gs thereof extending forward atv'th outersides of each of the sides oftheA band llaanl-, pivotallymounted at Isa for rockto a finger 23 and the screw is mounted upon a bracket 24 both of which are soldered or otherwise permanently secured to the band |'.I The i 1 yieldability of the roller 2D permits the passage of bent or mutilated coins.

A horizontal rod 25 is located above the upper end of the coin magazine 8 and is secured to and extends between frame sides l and 2. A shorterv rock shaft 26 is mounted on the side 2 anda supporting bracket 26a connected with the frame bar d 6 (Fig. 1) being located a short distance below the rod 25. A hub 21 is rotatably mounted on the rod 2,5 and carries a disk wheel `23 between two side plates 29. The disk wheel 28 is preferably of a semi-hard rubber and at its edge portions extends beyond the plates 23, which are of metal. ,Aplurality of spaced pins 39 are secured to one of the side plates l29 so as to pass over the arm having location close to the edges of the plate `29. The lowermost portion of the edge of the disk '23 comes into frictional engagement with the uppermost coin in the magazine.

A ratchet wheel 3| is connected with a hub 21. A pinion 32 is mounted for rotation on the rod I25 and has connected thereto one side 33 of a U- shaped stirrup, the two sides of which are integrally connected at their outer ends by the cross member 34. A stop 35 is permanently connected with the upper frame member 3 and extends at the front side of the cross member 34, limiting its forward movement. A spring actuating dog 3E is lconnected to the stirrup 33 and bears against the toothed edge of the ratchet wheel 3|. A spring stop member 38 engages with the edge of the ratchet wheel, being located opposite the dog 36 preventing movement of the wheel except in one direction. 1 A gear 39 mounted on the rock shaft 26 is in mesh with the pinion 32. At the outer end of the rock shaft 26 an arm 40 is connected, to which a coiled tension spring 4| is secured at one end and is anchored at the other end, thereby tending to resist turning of thegear 39 in a counterclockwise direction (Fig. 2) and, when thus moved, turning it back in a clockwise direction, when free todo so. v AA plate 421s permanently connected with the rock shaft 26 extending upwardly and forwardly therefrom. A plurality of connecting rods 43, shown as ve in number and threaded at their upper ends, pass through spaced openings in the plate 42 and through sleeves 44 above the plate, adjusting nuts being on the rods above the sleeves. Said rods at their lower ends are connected each to a manually operable lever 45, ve of them a-s shown, all mounted for rocking movement at their inner ends about a shaft 46 permanently secured tothe frame plate 2. Each of the levers is acted upon by a tension spring 41 tending to lift the levers to upper position. YThe levers 45 have finger engaging horizontally pvstoneduter ends and each maybe independently manually oper- Mei y., lhe mechanism. may behoused within anvsliilr able' housing .generally `but not-specifically` dis- 4 closed in the drawing, said levers traversing vertical slots in the front of the housing. Also at the front of housing and above the levers and extending through said housing is a coin receiving cup 43, from which a chute 50 of tubular form extends upwardly and inwardly to the upper end of the coin magazine 8 at its front and between the sides of the band l5 in a position to receive the coins which are moved horizontally forward at the upper end of the magazine to the chute, through which they drop by gravity to the cup 49.

In the operation, the magazine 8 is lled to any desired amount with a plurality of coins 5| disposed horizontally one over the other. The spring actuated plunger I9 in the lower part of the magazine forces the coins upwardly so that the` uppermost one comesl to the flanges I6 and is pressed against the lower edge of the disk 2B. It will be noted that the connections of the rods 43 to the levers 45 are at progressively further distances from the rod 46 about which they are moved.

On depressing any selected lever 45 of the bank of levers described downward, the plate 42 is likewise moved downward rocking the rock shaft 26 and turning the gear 39 in the same direction, thereby actuating the pinion 32 in the opposite direction to move the dog 36 in a clockwise direction. The dog 36 engaging the ratchet wheel turns the ratchet wheel and the disk 28 in a clockwise direction (Fig. 2) so that the uppermost coin engaged by the disk is frictionally moved in a forward direction and delivered to the chute. If the lever farthest to the left in Fig. 3 and the one having its rod 43 -connected nearest the rod 46 is actuated, the movement of the plate 42 is suicient that only a movement of the ratchet wheel 3| in one step of movement occurs and one only of the coins is taken from the magazine and delivered to the coin receiving cup 49. With operation of the next adjacent lever to the right of the rst one described as actuated, the movement of the dog 36 is sucient to turn the ratchet wheel and the disk wheel twice as far as with the first lever mentioned. The uppermost coin is ejected from the magazine from the chute 50 and with continued movement of the disk wheel 28, the succeeding coin is also delivered, the finger |8 on the arm which has been bearing by gravity against the side of the uppermost coin comes into engagement with the next succeeding coin when the uppermost coin has been moved partially over the roller 29 to the chute 5U, and the linger |8 is forced against the next succeeding coin by a pin 30 riding upon the upwardly widened free end portion of the arm I 1. The design of the connection of the rods 43 to the levers 45 is such that there is a progressively increasing throw of the iir'st lever, that is, the rst lever will cause a movement of a dog 3B a predetermined distance to eject one coin, the second twice as far, the third three times as much and fourth and fifth, four andfve times as much respectively. There-V fore, the number of coins which are delivered may be selected in any number from one to five by selecting the proper lever 45 for operation.

The magazine is readily removed from its spring holding clips, 1, the sleeve |3 detached from the magazine, the pin l forced to the bottom of the slot 9 and the magazine replenished with coins wherever needed after which the sleeve 3 is replaced and the plunger l0 released to push the uppermost coiriinv the magazine against' the flanges i8.- f The Structure-described is practical and eiective and is'-lcuiltV-atv lowcost. #One of the ma:
